| Abstract | PURPOSE. To assess function of the central retina in 10-week-old infants, multifocal electroretinograms (mfERGs) were re-corded. mfERG responses represent postreceptor retinal activ-ity. METHODS. In infants (n 23) and adults (n 10), mfERG responses to both unscaled and scaled 61 hexagon arrays were recorded. Amplitude and implicit time of negative (N1, N2) and positive (P1) peaks of the first-order kernel were examined. The response from the entire area stimulated and responses to concentric rings were analyzed separately. The overall aver-aged response of the first slice of the second-order kernel was also evaluated. Results from infants and adults were compared. RESULTS. Amplitudes of the infants ’ responses (N1, P1, N2) were significantly smaller and implicit times were significantly longer than those of adults. In infants, amplitude and implicit |
